 EPOXY and POLYURETHANE injection  


Rocco 1500 is a hydrophobic water cut-off grout based on a MDI (methylene-diphenyl-isocyanate) polyurethane.The resin is 100% solvent free and 100% solids.

Upon contact with water Rocco 1500 reacts to a foam with a very fine cellular structure while expanding its volume up to 40 times. The induction time is approximately 15 seconds after water-contact (20° C) and the cure time is approximately  45 to 60 seconds at 20° C. Changes in temperature effect the lnduction and cure times.



Rocco 1500 reacts well with water of alkali qualities up to ph 13. The cured material is semi flexible and of a constant volume. Since water is not a component of the foam structure,the cured material is essentially not effected by water or dryness. The reacted material does not shrink or swell. Therefore eliminating the problem of dry-shrinkage observed in hydrophi1ic products.


 

Rocco 1500 offers a high resistance against many chemicals and is essentially non-toxic when fully cured The product is compatible with steel,foils, bituminous materials, cable insulations and most solvent free injection materials.

Rocco 1500 is approved for drinking water contact according to the recommendation for large and small surface sealants.
